Introduction While testing a VHDL module, the declared input/output ports should be tested as much as possible against all possible scenarios. For example, if a module you are designing has 5 input and 1 output ports, all input signal combinations that can enter these ports should be tested for a completely reliable design. However, the number of input combinations can reach hundreds of thousands, maybe millions for some designs. Of course, it is not possible for us to consider all combinations for these situations. Different methodologies are applied for such… Daha fazlasını oku »How to Use txt files in VHDL Test Bench?
